ALT Landsat image of Key West, Florida. Small bits of land extend from the left side of the image out into the ocean. The shallower areas appear lighter blue and darker areas are darker hues of blue and green.

ALT Map of bathymetry data for that same area of Key West, Florida. Dry land is white. There are large areas of dry land in Key West and a few other patches scattered throughout. The shallowest areas, less than a few meters deep, are pale yellow green and are mostly just offshore. Deeper areas are shown in progressively darker shades of blue. The result is patches and swirls of deeper and shallower areas mixed together, as well as a few deeper channels that bisect shallower areas.
